Application & Dosage
In the laboratory, anhydrous sodium sulfate is widely used as an inert drying agent, for removing traces of water from organic solutions.
Simply mix Sodium sulfate into solvent and stirr properly, all moisture will absorbed by sodium sulfate. Principal behind that is Sodium Sulfate Crystals consist of [Na(OH2)6]+ ions with octahedral molecular geometry. These octahedral share edges such that eight of the 10 water molecules are bound to sodium and two others are interstitial, being hydrogen bonded to sulfate. These cations are linked to the sulfate anions via hydrogen bonds.
Sodium Sulfate also widely used as LAUNDRY CHEMICALS.
Sodium sulfate is an important compound of sodium. When anhydrous, it is a white crystalline solid of formula Na2SO4. The deca hydrate, Na2SO4•10H2O, is known as Glauber's salt. Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping, although it has many other uses
